堆栈溢出错误.使用winforms

我的程序中出现堆栈溢出错误。我有一个带有函数和属性的类，我需要我的带有winform文本框、复选框等的分部类才能访问。当我建立它是好的，但我得到一个运行时错误。它指向我在winform中使用的默认构造函数，以及VisualStudio声明堆栈溢出的位置。代码：

public class TeamCreator:Form
    {
        //fields
        public string[] players=new string[12];
        public int[] points=new int[12];
        public int currentPlayerScore=0;
        public TeamCreator()//default constructor
        {
            for (int i = 0; i < 11; i++)
            {
                this.players[i] = "";
                this.points[i] = 0;
            }
        }
        public TeamCreator(string[] teammates,int[] scores)//construct Team object with user input
        {
            this.players = teammates;
            this.points = scores;
        }
        public void setTeammates(string player,int index)//set players array
        {
            this.players[index] = player;
        }
        public void setPoints(int[] scoreList)//set points array

            {

            return listOfPoints;

        {
            int total=0;
            for(int i=0;i<11;i++)
            {

            }
            return total;
        }
        public double meanPoints()//returns mean or average of total points
        {
            int total = this.totalPoints();
            int mean = total / 11;
            return mean;
        }
    }

对于我为什么会出现这个错误以及如何修复它，我们将不胜感激。我对C#有点陌生，所以不确定问题出在哪里。
